"It's not polite, but it's what we're all thinking and it's what it will take to get their attention," Davis' campaign wrote in a blog post about the ad.

On his campaign website, Davis touted his record on gun control, detailing his work to pass a law that allowed police to investigate shooting threats made online. He said that preventing gun violence is a top priority for his campaign and listed endorsements from various gun-violence prevention groups.

The NRA slammed "Desperate Davis" in a response video on Twitter, asking if he needed a bar of soap after hearing his "foul message" played over circus music.

The ad aired unedited and uncensored on Albuquerque television station KRQE-TV. Bill Anderson, the station's general manager, said in a statement that KRQE was required by federal law to air the spot as-is.

"This station, by law, is not permitted to censor or in any way edit this commercial. What we can control, however, is the 15 seconds of airtime preceding it, which we will use to warn the viewer of a possible offense, explain our own views, and cite the federal laws imposed on candidates and TV stations," Anderson said.

Albuquerque residents interviewed by KRQE were split as to whether the ad was appropriate, though multiple viewers voiced their displeasure with the ad on the station's Facebook page.
